Leadership always contains far more down cycles than ups. Lincoln, Jefferson, Washington, Wilson, and both Roosevelts experienced setbacks that would have discouraged (the) less resilient.

Aristotle turns out to be an extremely practical guide for those asking such personally profound questions, like: What should I do next to find meaning and fulfillment in the next stage of my life?. He offers timeless advice to business people who want to be successful both at work and in their private lives. For example, he shows how business leaders can create successful organizations and, at the same time, behave ethically. Come to think of it, the CEO of Wal-Mart should study Aristotle!

Sadly, too many corporate leaders still believe that the way to boost productivity and profits is to continually reduce salaries, benefits, and training expenditures, a strategy that can be taken only so far. At a certain point in a developed society, salaries and benefits can't be slashed further and, in the long term, comparative economic advantage then must be realized through the effective mobilization of an educated, engaged, and loyal workforce.

When we spoke about workplaces in 1972 we mainly were referring to old-line manufacturing firms, on the one hand, and Main St. shops and restaurants, on the other. Both of those categories are now insignificant in terms of employment. Today, the economy is dominated by the rapidly growing Low-Cost Operators - national discount and mall chain stores, fast food franchises and supermarkets - which offer employees low salaries, few benefits and little training.

Motorcycle manufacturer Harley-Davidson is a prime example of an American company that uses employment conditions to boost productivity. Current CEO James Ziemer - who started with the company while in high school has negotiated imaginative contracts with the unions representing Harley's workers, agreeing to keep production in the U.S. in exchange for constantly reducing total labor costs through automating tasks and changing work rules. Because Harley regularly reassigns workers whose tasks have been automated to other parts of the company.

The status of women in the workplace has improved dramatically since 1972. More women today have good jobs, the gap between the incomes of men and women has been markedly reduced, and women are reporting far higher levels of job satisfaction.

By all indications, American business leaders are more adept at creating business strategies than they are skilled at human capital management. American entrepreneurs are world-beaters when it comes to creating new businesses, and corporate managers are adept at using the latest marketing, financial, and technological practices.
